Security guard services provide a layer of protection for data transfer and system resources in the Internet. They are defined by the ITU-T X.800 Recommendation. A security service ensures adequate security of a system’s internal and external components, as well as data being transferred between them. This article explains what security services are and what they do.
Provides authentication of a communicating peer entity and the source data
Peer entity authentication is a service that helps a peer entity confirm its identity. It can be used during connection establishment or during the transfer of data. It provides confidence that the entity is not masquerading or replaying the connection. Peer entity authentication can also help establish trust between two entities that communicate with each other over the Internet.
Provides confidentiality of selected fields within the (N)-user-data on an (N)-connection or in a single connectionless (N)-SDU
A scalar function returns a single scalar value, and it can be referenced in a SQL statement wherever an expression is allowed. The data contained in a scalar is either a string or a numeric value, or it can be a combination of both.
A sequence number uniquely identifies a record or frame within a source member. This number is assigned by the system and begins with one. It increases sequentially until the source member is altered, or the user resets it. This sequence number page allows the user to specify which records should be read in which order.
An integrity assurance service is provided by the (N)-layer and supports integrity of the (N)-connection or single connectionless (N)-SDU. It protects the integrity of selected fields within the SDU, and may detect unauthorized modifications or replays. It also provides the recipient with proof that data has been received by the intended recipient.
A service data unit is a set of data that is passed from one layer to another. A service data unit contains a payload, header, and footer, and can be used to identify a service. It is a protocol used by service providers and clients to advertise their services. The protocol also provides information to the user.
A system resource management database stores hardware information, including vital product data and topology and location information. This database also provides a means for users to manage system resources, including devices and storage areas. The system resource management group controls the use of these resources. This database contains the names of the system and devices and the functions performed by each.
A subroutine is a sequence of instructions in a larger program. A subroutine can be repeated or used in more than one program. A subscript is a printed half-line below the normal printing line. Its syntax varies depending on the platform. For example, a subscript contains a chemical formula.
A logical unit determines whether a program has the ability to allocate system resources. Asynchronous messaging, on the other hand, is a way of communicating between programs. It involves sending and receiving data, which requires a program to wait for a response from another. Moreover, asynchronous processing consists of a series of operations or interactive job.
